2.4.2 Memory configurations

You may install 64MB, 128MB, 256MB, 512MB, and 1GB DDR DIMMs into the DIMM sockets using the memory configurations in this section.

Important notes

1.Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations in Table 1.

2.In dual-channel configurations, install only identical (the same type and size) DDR DIMM pairs for each channel.

3.Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

4.Make sure that the memory frequency matches the CPU FSB (Front Side Bus). Refer to Table 2.

5.DIMMs installed into any three sockets will function in single- channel mode.
